Subroutine SIGINI doesn't work...

Subroutine SIGINI doesn't work...

Subroutine SIGINI doesn't work...

(OP)
Hello !

I would like to use subroutine SIGINI in Abaqus Standard. I create a simple model without load, only SIGINI prestress.
So, I add in .inp file :


** INITIAL CONDITIONS
**
** Name: BC-3 Type: Stress, user


just before STEP and after Boundary Conditions. (see carre_precontr.inp in attachment)
The subroutine used is very simple, just sigma(1)=500. (see precontr.f in attachment)
I attach subroutine file containing SIGINI to the job :

abaqus job=carre_precontr user=precontr.f


My job runs neither warning nor error : "job completed successfully".

BUT, when I open .odb file in visualisation, the result is the same withor without SIGINI (stress=0 , displacements=0 , ...).
Do you know why ?
I want my subroutine to become activ, how I do that ?

Regards

Laura

Hi,

Double star "**" means comment and all lines starting with "**" will be ignored.

You need to use something like:

*Initial conditions, type=stress, user

Please see the Keywords manual for exact usage.

Best.

Thank you. I didn't see this mistake.


But, even they are only one star "*" :

** Name: BC-3 Type: Stress, user
*Initial Conditions, Type=Stress, User

I have the same result (stress=0, displacements=0, ...)


NB : When I import the input file, I have this warning :

The model "carre_precontr" has been created.
The part "PART-CARRE" has been imported from the input file.

WARNING: The following keywords/parameters are not yet supported by the input file reader:
---------------------------------------------------------------------------------
*INITIALCONDITIONS, TYPE=STRESS
The model "carre_precontr" has been imported from an input file.
Please scroll up to check for error and warning messages.


So the initial conditions can't to be read. I don't know why. Do you have any idea ?

Regards
